Free Loan Calculator


A loan calculator is a useful tool for estimating the monthly payments and total cost of borrowing for a loan. It helps you understand how much you'll need to pay each month and the overall cost of the loan based on various factors such as the loan amount, interest rate, and loan term (duration).

Here's a simple formula for calculating monthly loan payments:


  • is the monthly payment.
  • is the principal loan amount (the initial amount borrowed).
  • is the monthly interest rate (annual interest rate divided by 12 and expressed as a decimal).
  • is the total number of monthly payments (loan term in months).

To use a loan calculator, you can follow these steps:

  1. Input the loan amount (principal).
  2. Input the annual interest rate (as a percentage).
  3. Input the loan term in years (or the number of months).
  4. Click the "Calculate" button.

The calculator will then compute the monthly payment and may also provide you with a breakdown of how much of each payment goes toward the principal and how much goes toward the interest.

Many financial websites and apps offer online loan calculators that make it easy to estimate your monthly payments for various types of loans, such as mortgages, car loans, personal loans, or student loans. These calculators may also allow you to adjust additional parameters like extra payments, down payments, or different compounding frequencies for interest.

Using a loan calculator can help you plan your budget and understand the financial implications of taking out a loan. It's a valuable tool for making informed financial decisions.
